'BRACELET.

SPBCIPICATION forming part of Letters Patent No. 303,581, dated August12, 1884.

Application filed April 10, 1884.

To tZZ whom it may concern Bc it known that I, O'r'ro MILLER, ofProvidence, in the State of Rhode Island, have invented an Improvementin Bracelets and Similar Articles of Jewelry, of which the following isa specification.

My invention relates to that class of bracelets in which the arms of thebracelet are hinged or pivoted to a central ornament, and closed uponeach other by means4 of springs; and it consists in the'inprovedconstruction of the arms and their operating-springs, as hereinafterfully set forth.

Figure l is a side elevation of my improved bracelet. Fig. 2 is a topedge view ofthe same. Fig. 3 is a section of the central box to whichthe arms are secured, showing au edge elevation of the joint-piece. Fig.4 isa detail View showing the interior of the central box and a planview of the attached jointpiece. Fig. 5 is a plan View of one of thebracelet-arms, partially formed. Fig. 6 is an edge view of the same.Fig. 7 is an edge clevation of the same when bentto the proper form forthe bracelet. Figs. 8 and 9 represent plan and edge views of amodification of the joint-piece.

In the accompanying drawings, A A are the two opposite curved arms ofthe bracelet, and B the central box or ornancnt, to the opposite sidesor ends of wlich the arms are attached, so as to be capable of anopening and closing movement. The arms A are each secured to ajoint-piece, C, which is soldered or otherwise secured to the bottomplate, a, of the box B. I preferably construct the joint-piece C in bentform, as shown in Fig. 3, the upper end portion of the same beingadapted to form a stop k and cover for the .j oint.

The joint-piece is provided with the opposite pintlesf-b b, adapted toenter the open hooks c of the bracelet-arms, thus forming a pivot orhinge for the bracelet-arm.

Midway between the opposite ends of the pintles Z b is located theforward-projecting lip d, and at the base of the lip d is formed adownwardly-projccting stop-piece, c.

The arms A ofthe bracelet are first formed with a spring-tongue, f,intermediatc between the joint-arms g g, as shown in Figs 5 and 6, andthe thinned ends, 71.71,, of the joint-arms 'tongue andjoint-arms madein one (No model.)

are then turned in the form of a hook, c, as shown in Fig. 7,preparatory to attachment to the pintles 7) b of the joint-piece O; and

the end, i, of the spring-tonguef will abut against the stop c, as shownin Fig. 3, whenever the bracelet is closed, as shown in Fig.` l, andthus serve to prevent further inward movement of the arm; and thepressure exerted by the spring-tongue f against the under side of thelip d will serve to maintain the closed position of the bracelet-arms;and when the said arns are thrown back to their opened position, asshown by broken lines in Fig. 1, the resilience of the spring-tongue fwill, upon the release ofthe arms, bring them back forcibly to theclosed position,'as before. The spring-tongue f may be either madeintegral with the joint-arms g g, or formed of a separate piece ofmetal, as preferred.

The box B of the braceletis provided with the opposite openings, jj,adapted to receive the rear end, 0, of the joint-piece O; and amodification of the said joint-piece is shown in Figs. 8 and 9, in whichthe bent upper portion of the same (shown in Fig. 3) is dispensed with,and the joint-piece is made in a single'plane, as shown in the edgeview, Fig. 9; and in this case a separate piece may bc soldercd orotherwise secured to the side or end of the box, to take the place ofthe stoppiece 711. (Shown in Fig. 3.)

I do not of course confine. my improvement to the manufacture ofbraeelets, as it is equally adapted for finger and scarf rings, andother similar articles of jewelry.

I claim as my inventionl. In a braceletor ring, the combination of thecentral box or ornamcnt with the opposite curvcd arns provided with aspringpiece, substantially as described.

2. In a bracelet or. ring, the combination of the central box orornanent with a jointpiece provided with the opposite pintles, theforward-projecting lip, and the downward stop, substantially as and forthe purpose set forth. i

3. The combination of the opposite curvcd arms provided with thejoint-arms and an intermediate spring-tongue, with the joint-piece IOUprovided with the opposite pintles, the forward-projecting lip, and thedownward stop, substmtzdly as described.

4. The combination ofthe central box or ornzunent provided with anontn'ardly-pro jeeting lip and the downward stop, with the pivotedopposite arms provided with 'ile j ointarms and the intermedmtespring-tongue, Substantzdly as described.

OTTO MILLER.
